iPhone keyboard not working during phone calls, how to fix my iPhone keypad response?

Someone working at a restaurant Posted on Jul 30, 2018 11:55 AM this

question that I copied/pasted above. And today, Sep 2, 2022, I am

reaching out on the same question.

Please understand, I have a slightly different case, but I think exactly the same technical

problem.

I was answering a callback from Apple Support on a

totally different Subject, and I could not respond by clicking on the

"1" on my telephone keyboard (keypad). I could answer my

iPhone and hear the prerecorded message from Apple (Was I ready now),

and I wanted to respond with "1' on my keypad, but Apple

pre-recorded voice message came back and asked again, then paused

silently while I pressed "1" again, then another

pre-recorded message Apple could not hear any reply and my call was

dropped.

By the way, my unrelated question to the Apple

Support Chat person concerned help I needed to understand the

different items like AppleCash, ApplyPay, AppleCard and funds from an

Apple gift card I can use in the App Store. I was trying to

understand how I was paying for iCloud storage, and how that works.

This Chat person suggested the Voice option would be better for me.

I received the callback and could answer my iPhone. However, I was

prompted in the call to select "1" if I was ready now (or

some similar question). The Apple call could not see or hear that I

clicked "1" on my keypad nor could it hear me speak

"one".

After several tries, which required me to

get back to a Chat person, that person asked if I could use a

different phone, and I used my friend's iPhone for a callback. I had

no problem selecting "1", and then talking to an Apple

Support person who was able to kindly help me understand the methods

to Apple pay and how I could use my credits up from my Apple Gift

Card, and then it would take funds from another method I already had

authorized.

"Besides just doing a reset on the phone what have

you tried? I would try creating a current backup of the device and

then restoring this backup.

This Chat person responded

several times, and the last chat, I copied to my paragraph above.

I do not know if this solution of backing up my iPhone (which I can do)

and restoring it (which I am not sure I can do) will work. I

occasionally have had this issue on my iPhone during a call where my

response to a prompt was not heard, but other times, no problem.

Is there a known solution for this problem?

Also, could I benefit from visiting an Apple Genius Bar for help? I am a

senior and I have had 3 Apple iPhones and 2 iPads since 2012. So, I

have experience with Apple iPhones but now, not so easy for me.
